Without a stable and long-term power supply system to ensure the normal operation of computer and network communication equipment and related peripherals after they are put into service, serious political and economic consequences will inevitably result. A high-quality and efficient power distribution environment plays a crucial role in a computer room. Therefore, the power distribution system in a computer room is the heart of the entire room and a key aspect of computer room engineering. The reliability of computer system operation must first and foremost guarantee the reliability of the power supply and distribution system.

A computer system consists of a central processing unit (CPU), servers, and highly sophisticated peripheral devices, all composed of numerous complex, densely assembled electronic components. Due to its complexity, it's difficult to avoid failures in any part of a computer system. Therefore, the reliability of computer systems is a core issue affecting the development and application of computers. The reliability of computer room engineering is inextricably linked to factors such as the room environment, power supply and distribution, and grounding. Improper handling of the power supply and distribution system and the grounding system will affect the reliable operation of the computer system.
